An eyeglass frame has four essential frame sizes (i.e. eye, vertical, bridge and temple see illustration) as follows:
- Eye Size - is the horizontal width in millimeters of the lens.
- Vertical Size (B) - is the vertical height of an eyeglasses lens.
- Bridge Size - measurement is the distance in millimeters between the two lenses.
- TempleSize - is measured along the length of the temple, from one end to the other, including the bend.
Frame Selection Guidelines
Matching Eyeglass Frames to Face Shapes
Everyone has different a face and the shape of your face will determine the frame shape that suits you best. The features of your face are important when choosing an eyeglass frame:
- The size of the frame should be in proportion/scale with your face size.
- Eyewear should match your personal best feature (such as a green frame to match green eyes).
- The frame shape can contrast with your face shape (against facial contours).
According to The Vision Council are seven basic face shapes: round, oval, oblong, base-down triangle, base-up triangle, diamond and square. Follow these guidelines:
- Round - A round face has curved lines with the width and length in the same proportions and no angles. To make a round face appear thinner and longer, select angular narrow eyeglass frames to lengthen the face, a clear bridge that widens the eyes, and frames that are wider than they are deep, such as a rectangular shape.
- Oval - An oval face with a rounded chin and forehead is considered to be the ideal shape because of its balanced proportions. To keep the oval's natural balance, look for eyeglass frames that are as wide as (or wider than) the broadest part of the face, or walnut-shaped frames that are not too deep or too narrow..
- Oblong - An oblong face is longer than it is wide and has a long straight cheek line and sometimes a longish nose. To make an oblong face appear shorter and more balanced, select frames that have more depth than width, decorative or contrasting temples that add width to the face, or a low bridge to shorten the nose.
- Base-Down Triangle - A base-down triangular face has a narrow forehead and widens at the cheek and chin areas. To add width and emphasize the narrow upper third of the face, select frames that are heavily accented with color and detailing on the top half or cat-eye shapes.
- Base-Up Triangle - This face has a very wide top third and small bottom third. To minimize the width of the top of the face, select frames that are wider at the bottom, very light colors and materials and rimless frame styles (which have a light, airy effect because the lenses are simply held in place by a few screws, with no surrounding frame material).
- Diamond - Diamond-shaped faces are narrow at the eye line and jawline, and have broad cheekbones that may be high and dramatic. This is the rarest face shape. To highlight the eyes and soften the cheekbones, try frames that have detailing or distinctive brow lines, or try rimless frames or oval and cat-eye shapes.
- Square - A square face has a strong jaw line and a broad forehead, plus the width and length are in the same proportions. To make a square face look longer and soften the angles, select narrow frame styles, frames that have more width than depth, and narrow ovals. Avoid square framed styles. However if your face shape is more rectangular then large, square frames could help your face to appear shorter.
Matching Eyeglass Frames to Face Colors
TheVision Council's three keys to color analysis are:
- All people have either cool (blue-based) or warm (yellow-based) coloring.
- Everyone looks best in his or her own color base.
- Eyewear color should complement personal coloring.
Matching Eyeglass Frames to Skin Undertones
The main factors that determine the best color palette are the undertones of the skin, eyes and hair, as follows:
- Skin - Undertone is the prime element in determining frame coloring. All complexions fall into one of two color bases - cool or warm. A cool complexion has blue or pink undertones, and a warm complexion has a golden or yellow cast. Olive skin is considered cool because it is a mixture of blue and yellow.
- Eyes - Eye colors usually are a secondary element in determining coloring because of the many variations of eye color. For example, blue eyes can range from a cool almost-violet to a pale blue-gray, which is warm. Brown eyes can vary from a light cider shade (warm) through a medium-brown to a cool almost-black.
- Hair - Hair colors also are considered warm or cool. Strawberry blond, platinum, blue-black, white, auburn, salt-and-pepper and ash brown are cool. Warm hair colors include golden blond, brownish black, brown-gold, red and "dirty" gray.
Based on your analysis:
- Frame colors best for warm undertones are camel, khaki, gold, copper, peach, orange, coral, off-white, fire-engine red, warm blue and blond tortoise.
- Frame colors best for cool undertones are black, silver, rose-brown, blue-gray, plum, magenta, pink, jade, blue and demi-amber (darker) tortoise.
More Eyeglass Frame Selection Tips
Some tips in selecting your eyewear frame:
- Plastic eyeglass frames are lightweight, versatile and cost-effective.
- Metal eyeglass frames are durable and depending on the metal, could be extremely light.
- Select a frame that make your face look oval.
- If you have a long nose then a frame with a low bridge will help to shorten the appearance of it.
- The top part of the frame should follow the shape of the eyebrow.
- If you need high prescription eye glasses then choose a small frame.
